What a great camera!!! Great tear down, awesome to see someone who knows what they are talking about do this.
Thanks for showing the part where you fixed it back up! Loved the whole episode.
It really is amazing at how much technology they have crammed into such a small space. It really shows that gopro cares to get out a quality product unlike some other manufactures. Great video, as a electrical engineering major, i definitely enjoyed it.
I think GoPro's main driving force is the number of high spec Chinese copies appearing for a quarter of the price with almost undistinguishable performance. Like the SJ4000 WiFi which beat GoPro to having a screen on the back.
Not to mention the load of extra functionality like control over things like white balance. If you do a UA-cam search for SJ4000 GoPro comparisons it's almost identical side by side footage.
bigclivedotcom Not so really. With SJ4000 and clones you never really know what you get. GoPro is more expensive, but it just WORKS. Optics are high quality and you actually have warranty too. If you have time to play around, you can save few dollars with SJ4000, but it's a joke when you need to do professional work.
***** Well I've got a GoPro hero 3 black and it has some glaring omissions like manual control over white balance? Instead it just creeps the balance about in the background with very odd colour effects on static images. Looking at the side by side comparisons on UA-cam I'm actually tempted to buy an SJ4000 and see how it compares to my GoPro for workshop videos. If anything the knock-off's are the boot that GoPro need to write leaner firmware for their cameras and add the painfully missing features.
bigclivedotcom to be honest, i bought an sj4000 from t-mart when they had them on sale for £30... not a bad price so i got one... it is really impressive, but if you then buy a gopro black 3+ (beats the sj4000 by a mile in my opinion) and just got my gopro 4 black with a detachable screen on the back, the quality of that is just in a completely different league to my sj4000... from what i can see, the sj4000 looks very sharp, almost too sharp... very jagged pixel-ation going on... where as both my gopro's have very realistic clarity, the colours don't have a ridiculously high dynamic range like my sj4000 has... i was so excited when i received my sj4000, its unbelievable for the price how good it is, but its incomparableto the new gopro's that are coming out
Jack Allen At that cost I fear you may have got one of the SJ4000 clones. (Yes, a clone of a clone). When it's so cheap it may look like the original and have the same name, but it may be just a cheap dashcam inside.
What a great video, I really enjoyed your knowledge and it was giving me some real insight into the toys we use all the time. I feel it is important to know how at least as much as my limited experience can, how things are made and what goes into the toys we use in our everyday lives. Love your website.
So impressive, the power consumption and the use of space, techporn for sure.
Very nice piece of equipment there. I'm glad to see they've finally added a screen to the back. Good teardown.
Beautifully done. I especially enjoyed your explanation of the elegance of the design, something laypeople like me just take for granted.
Thanks so much! Just used your breakdown to replace a scratched lens!
Fantastic teardown. Thank you. What a beautiful piece of gear.
"Don't Turn it on, take it apart ! " , awesome teardown Dave and the GOpro is the dogs nuts aint it cobber !
Loved the video, and the timelapse rebuild at the end was so satisfying. Keep it up!
Teardown... Saturday?
I'm okay with this.
Who cares what day it is, it's a teardown :D
CrownGamingAU Striking the UA-cam search terms before anyone else has a teardown up, this is a world first AFAIK.
EEVblog quick, do a consumer review!
EEVblog
Pqqqqqqpqpqqq+qq
I admire your patience. I'm prone to snapping clicky pegs off things while disassembling :S
As someone with the Hero3 Black, it's good to know the Hero4 Silver is basically the generation-jump comparison to the H3 Black.
And yeah, the 720p240 and 4K capabilities of the Ambarella A9 being limited to the H4 Black whilst the H4 Silver gets 720p120 and no 4K does make sense for keeping the thermal output of the chip a lot lower for the rather passive heat management in the Silver, whilst the Silver gets the LCD touchscreen and the Black doesn't.
It's rather hard not to drool over how beautifully designed the H4 Silver is, whilst watching the teardown. XD
Well done on the teardown, nice presentation, video and sound quality. One point if I may always missing from these teardowns is a little bit of detail, What is the smallest passive component on the board, smallest component pitch and PCB thickness?
16:55 , I think the FLIR TG165 scared you for life.
He did get the FLIR TG165 for free and he already owns a higher model.
So: Why be careful?
This GoPro seams to be paid with his own money and to be used for his other hobbies. So the teardown was not the main reason to buy it.
sarowie thanks Dave!
Best deep review of the Gopro 4 ever :D
Happy new week
Thanks for doing this tear down Dave! I live for these little camera's and use them a ton! Their performance in cold weather (i.e. Snowmobiling) still worries me. Back with the Hero 1 we could go for hours on one battery, but with all these newer ones it seems I only get maybe an hour or less of record time.
Looks like a great day to charge up the Sinclair, whack the GoPro 4 on and take a spin to see if the vibration dampening is any better. Have a great day Dave! Thanks for the teardown, interesting.
It's amazing on how much you can Put in such a small form factor... Good Job to GoPro!
About the heat dissipation: the lens itself is a "heat-pipe" itself and when you are using the waterproof case the heat go to the black "ring" around the lens!
Pretty cool and genious! (i discovered it becouse it get hot while doing 4k)
EEVblog Ive done alot of recording on a hero 3+. From my experiences the housing around the lens gets very warm after a short period. I think this is what they are using to dissipate the heat of the sensor. I believe thats why they changed the design of the hero 3 from that of the hero 2. It also works very well at keeping the lens from misting over, especially in under water shots
Thanks Dave. That was a pleasure to watch.
@EEVblog I do believe they're using the lens housing as the heat sink. Even when the camera is inside the waterproof housing you can feel the metal black square lens housing getting pretty hot.
thumbs up for the teardown
thx for the video
and HUGE thumbs up goes to the guys from GoPro for this very cool camera.
respect!
Dave, maybe you want to do a teardown of the China-Clone SJ4000 in comparison to the GoPro?
Nice. Please do a Hero 4 black teardown as well.
You can imagine how much better and more compact devices like this could be if we had more efficient batteries.
really cool to see a teardown of popular electronics and not just a wanky consumer review.
And 8 years later I ended up needing it 😂
Now i know why GoPro charge a premium price for this superb sub compact video camera.
The technology and research into designing this camera must have been very intense.
Love mine, it takes incredible video.
i fucking love EEVblog! Dave you're the best!
This was a great tear down, very interesting what was in there.
Looks like the first GoPro that has actually sharp image. Well done, well done, what do year we have now?
Nicely done Dave, thanks.
1:13 "and if we slide our tool in there *pop* bingo!"
Awesome video! Thanks.
@17:10 you assume its the A9...? I would have imagined they'd save costs by still using the A7 on the Silver (and ofcourse, the A9 on the Black). Keen to hear more from you on this...
Rehaan Phone Definitely A9. Even the Silver has twice the data rate of the Hero 3
EEVblog ah, thank you! Two more questions : What is that tiny battery in there for? Also, why do you assume it's a new sensor and not the same one? Thanks...
Rehaan Phone It's so you don't have to reset the time and settings on it every time you remove the battery.
I had a question about this too. I assumed that the reason the Black was $499 was to account for the cost of the A9 chip. Otherwise why would they have throttled the Silver to 4K 15 FPS if it had the A9 chip? I agree the sensor is definitely updated (sharpness tests between the 3+ and 4 show this) but I am not sure it is the A9 chip in the Silver.
Kutibh Chihabi To answer your question of "why would they have throttled the silver"? Two reasons i can think of : 1) Heat 2) Product differentiation - its all about making money after all (eg. some cars have the exact same engines, but are sold in different states of electronic tune and for a several $ difference)
Yes! This is what I just wanted to see today!
oohjeay a teardown without destroying the device :D
The first person with british accent that I understand! Hell Yeah!
Awesome teardown btw
+Kddv1993 He's Australian, mate.
+L4RRY LOL
Can you make a lipstick style housing for the the Gopro3 or 4? Motorcycle community would love it!
I really liked this teardown, thanks for the upload
I'm giving a big thumbs up, luv your videos. P.s did it go back together easily?
Great tear down, was a fun watch.
Great Video. No need to open it myself. Just watch your video.
Love a teardown, what a beautiful thing.
Wheres the polarized filter? Is it embedded into the sensor?
There is no polarizer on a camera sensor. On single chip sensor designs there is a Bayer filter mounted very close to the pixels. On three chip sensor designs there are RGB filters on the beamsplitter prism.
Like your style .... New camera.... lets open it up most of us wouldn't do it great stuff
EEVblog It would be interesting to see a comparison between one of these and a cheaper action cam. Something like the Jaycar equivalent.
You get what you paid for, overall quality is damn good.
Damn, that is some inspiring design right there
That shirt is freaking awesome!
Can you do a thermal analysis of the gopro with your Flir camera? And maybe compare the Hero 4 with Hero 2 if you still have it?
3zuli I currently don't have either!
HUGE improvement since go pro 1! ;)
I'm going to take a guess that this couldn't wait till Tuesday? Lol. It just seemed like you were so antsy to dive into that piece of equipment that you couldn't wait. Otherwise, this was an interesting teardown, thanks Dave.
14:07 The cost of the image sensor (IMX117CQT) is approximately $8.5 I think.
Great video! My wife pulled out her old Hero4 silver her friend tried to fix (shutter button was not working). I carefully pried it apart and can see there is a ribbon cable running from under the shutter button that is not inserted into it a port, any ideas how to get that back in there?
If a GOPRO 4 silver gets wet outside the plastic housing, would it be a good idea to open it up and let it air dry? Whats the chances it would still work?
My Go Pro , drop in water ....swimming pool with case opened !
in 2 weeks dosent turno on again . do you think if i open it , and put in rise ....could be turno on again ?
Wait for it, wait for it..... here it comes.... "and we are in like flyn!"
I wonder what's the second chip to the processor? Is the Hero4 Silver locked down and it can actually match the black's perfomance?
heyy man. great video. I'm trying to knock off some extra parts to reduce the weight on my drone. I wanna lose the lcd and housing. you think it's possible?
I don't know, but please let me know what you came up with! I'm interested.
Didnt wanna mess with the GoPro. I stripped my old Xperia of everything except the battery and motherboard. Its about 22 grams now. Before removing the LCD/digitiser I installed a self starting IPcamera and hotspot app. So I have FPV starting at boot without needing a touchscreen =D
Thank you! That's so cool! :)
sure =) Ill make a video about it soon. Stay tuned!
Fantastic teardown Dave - Thank you :-)
720p-120 is a limitation of the sensor, so I've heard.
Hi, great video. Could you do a video replacing the front lcd or how to just remove lcd. Ta Ian.
Was that the Victorinox explorer in the background.
0:30 correction: hero 3+ BE is it's equivalent, not the hero 3 BE
The 120fps might be a sensor limitation perhaps.
Dave, it is becoming more usual to loose reference of size in many of the shots on the videos. In this video I couldn't get a clear idea of the size of the camera, which seems to me very small, let alone the size of particular details like the mic, etc. Maybe you could show relative sizes when appropriate. Thanks.
13:20 It could be that it's easier to transfer heat directly from gold to air than through soldermask.
It would be interesting to use the lens holder as a heatsink. It would probably help keep the lens from fogging up in cold weather as a bonus.
great video, thanks. I have a hERO 4 SILVER with a broken display. Is it likely that the screen is glued to the back?
Wow, that was an awesome tear-down, thanks!
i start in 480p and cant belive it is srsl 480p, what the ? awesome quality, need to change my as100v
wonder if they bothered to use arm9 and 11 built in flash ip security features or if you could jump the boot loader pins and boot in usart or something or jtag and flash the chip to create diy 720 240 fps? would be an immense amount of work but if we know it has the capability. i guess it's just a matter of data and clock speed or memory bus speeds and clock speed. could be the chip manufacturer says it can do it but gopro realized it really wasnt feasible.
Please put in description that it is better to hold the front screen while lifting the front panel! i ruined my hero 3 that way
Can i take the speaker off one of my busted gopro 4 silvers and put it in my good gopro 4 silver were its speaker is not working?
at 17:20, that thermal interface material on the two smaller chips looks like it did not even make contact with the heatsink?
Hi , did you teardown the china Xiaoyi camera ? is that possible to do a compare? ~
"bet chore bottom dolla..." ;-) love the accent...
Cool video, but if the GoPro uses a Sony's sensor and so does Sony and other manufactures use the same on their cameras, why would the final video image look different as far as color or light sensitivity some cases? Thanks!
Well. The sensor reads the data from the light. But diffrent cameras use diffrent lenses that bend light diffrently, so diff 1.
The data is (unless raw function is available) tweaked and changed a bit, so diff 2.
Then the camera could save it in diffrent ways, with compression or without. 8 bot color or 16 bit, so diff 3.
If you could shoot with 2 camera with the same sensor in raw in the same file format, possibly even with the same lense or very similar, it will look almost the same!
Hi, do you know what chip is responsible for the LCD light? I have a Hero 4 Silver and the light is so dim, almost looks off. Have replaced the LCD but the problem never got solved, I think it has to do something from the board. Any info where to look at would be appreciated, thanks!!
how did u get rid of the dust particles between sensor and the optics? :d it's not manufacture cleanliness anymore in your lab.
I think that at some point when they will combine 3d printing of plastics and metals (both are real at this point) and make it work on the micron scale, they will be able to print the full device in one go. No screws, no wasted space. It will also mean the end of tear downs so that makes me sad. But that's a long time from now, so it's ok.
There is no known technology that could ever make this happen. At some point you have been misinformed, and the 3D printing industry does not mind that at all because it all adds up to more sales.
You could never print metals with the same heat/electrical conductivity with fusion technology, fusion creates lots of holes, and gaps, creating a very "dirty metal" you would need a technology that assembles metal on an atomic scale to match its natural counterpart.
ipissed You're thinking exclusively printing. I'm thinking of a machine that can apply the techniques that made the individual parts in one go. I may of had not been specific about it.
They make far more complex machines than what i'm proposing considering that a lot of the items within say a regular camera's structure are plastics and polymers.
As for the rest, if there are machines that mold and produce those i doubt issues would exist for implementing them.
In a sense, what i'm saying is a direct evolution of that damnable rubber casing they put on products to seal screw holes and seams.
Also, IMO, you shouldn't say never. If enough money is allocated you can bet your top dollar that within a few years they could make it happen.
aserta ["You're thinking exclusively printing... I may of had not been specific about it"]
You mean the part about when you wrote "I think that at some point when they will combine 3d printing of plastics and metals (both are real at this point)".
An overwhelming majority of people just trust the hype of 3D printing without any real knowledge of what it really is. I blame the greedy industry. Sometimes when you refuse to dispel inaccuracies you bolster them.
ipissed By that i meant the filament plastic printing and the metal methods you're aware of.
I have the impression you're only acquainted with the low to middle end of both technologies.
As for metal, i think you should check what NASA does with rocket parts printed in metal. Because if they use such items in a rocket, then a camera is easy.
You're also quite constipated by this, nothing i said is out of this world, it's just expensive because there is 0 implementation in the direction i pointed.
Like i said, enough cash and such a machine(the whole assembly to create a fully 3dprinted camera, the concept, the movie coming soon) is no longer concept.
But that's just my 2 cents based on what i've seen done.
***** I am an engineer/designer, and I specialize in prototyping. Your point about lost wax casting should actually give you a clue about just how far 3D printed materials differ from traditional manufacturing. Why don't you ask yourself why you would print in wax, then cast in molten if you could just print the same thing with the exact characteristics in the first place. You can't.
Now take that knowledge, and apply it to every aspect of engineering that requires all the characteristics of traditional materials, and suddenly you have a very different world.
Engineers design things around materials, we don't design things, and hope that a material exists to suit the need. Designing things in 3D materials means creating inferior products that are not worth the time, and effort if traditional manufacturing is both cheaper, and far superior.
I need a new camera for my videos, it's a nice camera but if I could afford it I probably still wouldn't buy one though because of one thing ... the lens is too wide-angle and has a "fish eye lens" effect. If it a less wide-angle lens or even had interchangeable lenses I would reconsider.
If you look at some of my recent videos like the mini dehumidifier or Ikea Led lamp one then you'll see it's not bad if you choose a setting that uses the central area of the array. The lens barrel is a standard CCTV type thread (12mm?) so there are lens hacks that also include adjusting the fixed focus for closer work. But they all involve a bit of brute force on the lens housing.
You can go and adjust the fov i believe or atleast you could with the hero 2, put it on 90 degrees and 1080p and it looks like a normal camera
Clem I love your videos and love the current set up and the way how you make do with what would normally be considered a crappie camera!
BBC600
The thing is the webcam I use is on it's way out, the picture now flickers and glitches out like something crazy, so I'm on the lookout for a new cheap but good camera. I could use my camcorder, thing is want to use I an external microphone and that camcorder doesn't have any connection for one, so I would have to have use a separate device for recording the sound like I used to do, but that's just too much hassle in the editing to sync the video and the sound.
CoolDudeClem Well the GoPro 3+ black that I've got has a facility to use an external microphone via an adaptor plugged into the USB port. I've also seen hacks for adding an external microphone in place of the one on the cheap clones.
Is this thing meant to be dropped from your hand?
So, the black edition is capable of higher framerate, but has no LCD?
Darren Jacobson Correct. LCD only in the Silver.
Can you put Hero 4 Black internals into a Hero 4 Silver housing making it a Hero 4 Black with a built in LCD screen?
That's what i wonder to
Oh Dave!! How about a Canon HF G10 teardown?
Maybe I should send in my old first gen Contour HD...
Nice one Dave !
Ambarella Chipset for "Corporation" inquiry only, not for small business and individual. Other option are Taiwan made Video/Image SoC chipset, could be cheaper and they allow small MOQ.
Hello, unfortunately I've broken my GoPro Hero 4 Black Edition Front silver plastic, do you know where can I buy it? can't find it nowhere
Have you tried eBay? If not, go to your local camera store, especially if they sell gopros, and they may be able to fix it for you.
Hi, do you have an idea what kind of internal microphone could fit in? Mine stopped working (on a GoPro 4 Black).
Thanks in advance.
EEVblog here is a teardown of the hero 4 black edition. Not as good as your teardown but there does not seem to be a huge difference on the inside.
awesome tear-down...!
It's interesting to me that they use Sony sensors, when Sony itself is competing heavily with gopro (via the Sony Action Cam lineup).
Unreasonable Steev That sort of stuff happens all the time in the industry. Each division of Sony has to make a profit how it sees fit. So you get the sensor division selling to everyone and anyone.
Your image of international markets and divisions seems to be ssome 50 years behind...
Hi, where would the IR filter be on the Gopro 4 ? on the lens or image senor?
You're a bit more careful with this than with the flir I see. ;-)
I'm sorry, what is the "pure markening" in phrase about LCD absence in black edition?
Is there an A7 or A9 in there.....many are saying the a7
